Hello, on my Travelmate 4002WLMI, the sbs module causes a lockup upon suspend/shutdown when loaded. Additionally, a kernel oops occurs when unloading the sbs module with "modprobe -r sbs", but not with "rmmod sbs". While i was able to fix the oops on module removal (a race condition similar to 757c968c4423, but now inside the ACPI EC driver), i was unable to find the cause for the lockup. I did however find out that the lockup does not occur when i reset the EC SMBus alert flag before calling the handler function, to i suppose the issue lies inside the sbs alert callback (maybe similar to add68d6aa9e2). I created a bug report (https://bugzilla.kernel.org/show_bug.cgi?id=217041) with more information attached, such as dmesg logs. Any ideas on what causes the lockup? Armin Wolf
